O you possessed of sturdy intellects, observe the teaching that is hidden here beneath the veil of verses so obscure.
— Dante Alighieri, Inferno IX:61–63, trans. A. Mandelbaum
This page contains links to lecture notes, in-class lecture slides, and related reading material. Lecture slides are in Adobe PDF format. You probably already have something that reads PDF files. If you don’t have a PDF reader for your platform, you can get one for free for Windows or Android. You don’t need one for macOS since Preview can render PDF files. You also don’t need one for the iPhone or iPad. If you’re using an Android platform and don’t have a PDF viewer installed, you can download the Google PDF Viewer, Adobe Acrobat, or any of dozens of other viewers.
Please let me know if you find any errors or unclear wording. Any corrections will be most appreciated.
